HENRY XV. XVATKINS, OF CLEVELAND, OHIO, ASSIGNOR TO THE VOLTAIC ELECTRICMANUFACTURING COMPANY.

ELECTRIC BELT.

SPECIFICATION forming part of Letters Patent NO. 351,233, dated October19,1886.

Application filed Xovember 21, 18E5. Serial No. 183,474.

To all whom it may concern:

Be it known that I, HENRY XV. \VATKINS, of Cleveland, in the county ofCnyahoga and State of Ohio, have invented certain new and usefulImprovements in Electric Belts; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and usethe same.

My invention relates to improvements in electric belts; and it consistsin certain features of construction and in the combination of partshereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view showing the edgeof the belt. Figs. 2 and 3 are elevations showing, respectively, theouter and inner sides of the belt. Figs. 4 and 5 are enlargedelevations, in section, respect ively, taken longitudinally andtransversely through one of galvanic piles. Fig. 6 is a view inperspective of the plates. Fig. 7 is a View in perspective of thehousing 0. Fig. 8 is a View in perspective of one end of the metal stripE. Fig. 9 is an inside plan of the pad I. Fig. 10 is aview in verticalsection lengthwise of the belt. Fig. 11 is a view in vertical section atright angles to Fig. 10.

A represents the belt, that is made to reach around the person, and ismade of any suitable material, usually of cloth. To this belt aresecured the galvanic or voltaie piles B, made of alternate plates ofzinc and copper, arranged in the usual manner with intervening strips offelt, blotting'paper, or other similar material, saturated with water orsome mild acid, such as vinegar. Of course I claim nothing on thevoltaic piles per so. My invention relates solely to the manner ofhousing, connecting, and attaching these piles to the belt.

C is a glass housing, made substantially in the form shown in Fig. 7,the legs of the housing having lugs c and shoulders c, the sides 0between the shoulders 0 being depressed, as shown.

A metal plate, D, usually of zinc, is folded in the manner shown in Fig.(5, leaving an opening between the folds for the passage of the belt.The cars d of the plate fit between the lugs c of the housing and theedges of the (No model.)

plate 11, between the cars, coming about flush with the sides 0" of thehousing.

In assembling the parts the plates D are strung upon the belt andlocated at suitable distances apart. Next, the housings C are placed,respectively, on the plates D in the manner aforesaid, and apiece ofcloth is wound around the housing and plate to secure these two partstogether. Next, a thin metal strip,

E, having shoulders c and tongues e,is placed in position, with thetongms 6 extending through the respective housings. The shoulders e abutagainst the inner edges of the housing, and the tongues are turned uparound the outer edges of the housing. (See Figs. 4 and 8.) The piles Bare slid endwise into the respective housings between the plates D andthe tongues e of the metal strip. The metal strip E forms an electricalconnection between the two piles. The strip E is so thin that it isquite flexible and readily assumes the desired form as the belt ispassing around the person.

F is a strip of thin cloth, stitched at the ends and at the centralportion thereof to the inside of the belt. To this strip is attached thepads G, that are merely pieces of cloth or other suitable material, toprotect the person from contact with the plate D. The housings C areinexpensive and insulate the piles from 83 the clothing and protect thelatter from the moisture of the piles.

Hard rubber or other non-conducting material might be used for thehousing, but glass is preferable on account of its durability and 85cheapness.

I is a pad, usually made of cloth and circular in form, and stitched tothe strip F midway between the voltaic piles. The pad has a lining ofthin rubber cloth and other mate- 9c rials impervious to moisture.Strips of cloth i. are stitched to the face of the pad along the edge ofthe latter, leaving the central portion of the face of the pad exposed.(See Fig. 9.) Pieces of medicated cloth, sponge, or other 93 suitablematerial may be applied to the face of the pad and the edges tuckedunder the strips i to hold the same in place, so that the medicatedmaterial will come next to the person. Meantime the pad, with its rubberlin- I00 ing, will protect the clothing from being soiled 4 by thelotion.

I am aware that a combined galvanic and medicated pad, consisting ofplates of zinc, felt, copper, and a medicated pad secured togetherwithin a common frame, is not new, and hence I make no claim to suchconstruction.

What I claim is- 1. In an electric belt, the combination,with

a voltaic pile, a housing for said pile, said housing being made ofnon-conducting material, preferably of glass, and having lugs anddepressed sides, substantially as described, of a metal plate,preferably of zinc, said plate being folded to embrace the belt andfitting between the lugs of the housings, said plate having depressedsides to correspond with the depressed sides of the housings, the partsbeing arranged substantially as described.
